I have 2004 S4R that came with 59M ECU. The ECU broke so I sourced used 5AM from M695 on ebay from a guy who installed Ducati DP ECU on his bike. I am going to flash the M695 ECU with 04-05 S4R DP Race Plus map as I have full Arrows and open airbox. I have the red key and the two black keys that came with my S4R and the original OEM cluster is on the bike.

What I need to know is if the M695 ECU flashed with the S4R DP map will work with my keys and the instrument cluster after I install it, or if I have to do anything using the red key to mate the ECU with the cluster and the keys in order for the bike to work._________________2004 Ducati S4R Desmoquattro 996cc

Dealers do not usually code DP ECUs to the keys. This allows you to sell the exhausts and ECU as a set. Then return the bike to stock. You will still have the immo in the clocks for partial security. Providing the ECU is virgin it will work on another bike. Not familiar with the later S4R but on other bikes trying to forward update to IAW5AM have come across neutral light problems and lambdas being fitted._________________This guy looks after my bikehttp://www.ducati-john.co.uk/
